Patent number: 11247346Abstract: A gripping mechanism includes a holder, a gripping roller, and a lever. The gripping roller is housed within the holder and grips an object between the roller and an inner surface of the holder. The lever releases gripping of the object by pushing the gripping roller upward. Preferably, the holder includes two plate sections which support a weight of the gripping roller. An opening is located between the two plate sections. The opening receives insertion of the object. One of the two plate sections is inclined relative to a vertical direction.Type: GrantFiled: February 24, 2020Date of Patent: February 15, 2022Assignee: KYOCERA Document Solutions Inc.Inventors: Koji Izumi, Hayato Mori, Masaru Takagi, Tomohiko Yamakawa

Patent number: 11173616Abstract: A gripping mechanism includes an inclined surface, a rolling element, and a facing gripping part. The inclined surface is a surface inclined to a vertical direction. The rolling element freely rolls obliquely upward and downward on the inclined surface. The facing gripping part is arranged to face the inclined surface and forms an opening space with an end of the inclined surface, the opening space being narrower than a diameter of the rolling element. The rolling element includes: a core member forming a core of the rolling element; an annular member that is provided around the core member and has elasticity; and a plurality of ribs each of which is interposed between an outer periphery of the core member and an inner periphery of the annular member, and forms a gap between the core member and the annular member.Type: GrantFiled: November 26, 2019Date of Patent: November 16, 2021Assignee: KYOCERA Document Solutions Inc.Inventors: Tomohiko Yamakawa, Masaru Takagi, Koji Izumi, Hayato Mori
